DOI: 10.1002/lno.11723
Abstract: Documenting anaerobic microbial metabolisms in hypersaline perennially ice‐covered lakes in Antarctica further refines the environmental limits to life and may reveal rare biogeochemical mechanisms and/or novel microbial catalysts of elemental cycling. We assessed rates of… read more here.

DOI: 10.1016/j.chemgeo.2018.05.025
Abstract: Abstract Biostimulated sulfate reduction is a promising strategy for remediating groundwater arsenic contamination. But biostimulation often induces pH changes alongside biogeochemical transformations of iron, sulfur, and arsenic, which all affect arsenic mobility and the efficacy… read more here.
